A New Jersey father dropped his son off at day care with an unexpected package in tow: heroin.

An employee at Michael's Energy Factory in Paterson contacted authorities after finding 48 packets of the drug inside the 2 year old's jacket Monday, according to news reports.

Police charged the 27-year-old father, Phillip Young, with child endangerment, according to Reuters. He's being held on $85,000 bail. Police say the child appeared unaware of the drugs and no other children came in contact with them, Reuters reports.

Parents expressed concern at the drug's proximity to their children.

"My daughter sees something on the floor, puts it in her mouth thinking it's candy - same thing could have happened here," parent Dulce Ibanez told NBC4 New York.

Heroin and other opiates made up 44% of all substance abuse treatment admissions in 2012, according to New Jersey's Department of Human Services.

Michael's Energy Factory had no comment when contacted by USA TODAY Network.
